Hello, I'm running perl v5.10.0. I have tried installing 804.026, 804.027, 804.028 as well as the svn Tk. I have had the same results with each version. Compile completes but 'make test' returns: cd pTk && make DEFINE="" LIBPERL_A="libperl.a" LINKTYPE="dynamic" OPTIMIZE="-O3" PREFIX="/usr/local" PASTHRU_DEFINE="" PASTHRU_INC="" cd zlib && make libz.a "CC=cc " RANLIB="/usr/bin/ar s" make[2]: `libz.a' is up to date. make all-am make[3]: Nothing to be done for `all-am'. make[2]: Nothing to be done for `all'. cd jpeg && make libjpeg.a make[2]: `libjpeg.a' is up to date. make[2]: Nothing to be done for `all'. /usr/local/bin/perl "-It" "-MTkTest" "-MExtUtils::Command::MM" "-e" "check_display_harness; test_harness(0, 'blib/lib', 'blib/arch')" t/00wmcheck.t t/JP.t t/KR.t t/Require.t t/Tkxs.t t/Trace.t t/X.t t/adjuster.t t/after.t t/async.t t/autoload.t t/balloon.t t/bind.t t/browseentry-grabtest.t t/browseentry-subclassing.t t/browseentry.t t/browseentry2.t t/button-tcl.t t/button.t t/canvas.t t/canvas2.t t/coloreditor.t t/create.t t/cursor.t t/dash.t t/dialogbox.t t/dirtree.t t/entry.t t/errordialog.t t/exefiles.t t/fbox.t t/fileevent.t t/fileevent2.t t/fileselect.t t/font.t t/fork.t t/geomgr.t t/iso8859-1.t t/leak.t t/list.t t/listbox.t t/listvar.t t/magic.t t/mega.t t/msgbox.t t/mwm.t t/optmenu.t t/photo.t t/pixmap.t t/progbar.t t/property.t t/regexp.t t/rotext.t t/slaves.t t/table.t t/text.t t/textundo.t t/trace1.t t/unicode.t t/widget.t t/wm-tcl.t t/wm-time.t t/wm.t t/zzHList.t t/zzPhoto.t t/zzScrolled.t t/zzText.t t/zzTixGrid.t make: *** [test_dynamic] Bus error

Can you retry again, but first remove the "check_display_harness;" call from the Makefile (there should be two places). Do you have a core dump? If so, can you load the core dump into gdb or similar and show me the backtrace?

Hello, Has there been any progress on this bug? I am running perl 5.8.9 and I see basically the same as tkoger when trying to install Tk 804.028. I get a make: *** [test_dynamic] Bus error when trying make test. Removing "check_display_harness;" from Makefile, PNG/Makefile and JPEG/Makefile results in the Bus error going away, but most of the tests fail.

Hello, I've tried a few more things. I updated perl to 5.10.0 and rebuilt all modules and reinstalled a couple of other things that looked vaguely perl-related. make test still results in a Bus error. p5-tk from macports installs, but any attempt to use the module results in Bus error. I made the file test.pl: {{{ #!/opt/local/bin/perl use Tk; print "Hello World/n"; }}} {{{ $ perl test.pl Bus error }}} Running in gdb results in: {{{ $ gdb perl GNU gdb 6.3.50-20050815 (Apple version gdb-962) (Sat Jul 26 08:14:40 UTC 2008) Copyright 2004 Free Software Foundation, Inc.

The problem with initialisation is related to some odd code in Tk/MMutil.pm. For some reason I don't understand the module modifies the link line to force each bundle file to be linked against libperl. By default perl does not build a shareable library so in that case each bundle (Tk::Event, Tk etc) gets its own private libperl. When the perl binary dynamically loads the Tk bundles the perl state in the main binary does not map to the bundle so the module itself segvs because none of the perl infrastructure is initialised (the bundle can't see the parent perl state). Commenting out line 301 in Tk/MMutil.pm (I'm using the developer build) fixes most things for me. if ( -e "$Config{'archlib'}/CORE/$Config{'libperl'}" ) { # $self->{'LDDLFLAGS'} .= " -L\${PERL_ARCHLIB}/CORE -lperl "; } At least most tests now pass (using bleadperl compiled with 64-bit mode enabled). I have no idea why there is a need to link against libperl. Maybe Tiger or Panther behaved differently. As a final note, this works with /usr/bin/perl because the Apple perl is built using a shared library. So an alternate fix in the short term is for you to rebuild perl using a shared library. Hope this helps everyone.
